A cabinet is formed by fitting a protruding portion 21 on a rear cabinet 2 side to an inner side of an edge portion 12 of an opening on a front cabinet 1 side. Convex portions 4 provided at a plurality of positions on the obverse surface of the protruding portion 21 form a gap between the obverse surface of the protruding portion 21 and the reverse surface of the edge portion 12 of the opening at the fitted portion. The top portion of each of the convex portion 4 is formed in a tapered or arcuate shape. The convex portion 4 may be formed of a pair of projections provided at two adjacent positions.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A cabinet for acoustic equipment, the cabinet comprising: a first cabinet; a second cabinet having an opening covered by the first cabinet; a protruding portion disposed in an edge portion of the first cabinet, the protruding portion of the first cabinet engaged with an inner edge portion of the second cabinet; and a plurality of convex portions disposed on one of an outer surface of the protruding portions and the inner edge portion of the second cabinet, the plurality of convex portion sandwiched between the outer surface of the protruding portion and the inner edge portion of the second cabinet to form a plurality of clearances between the outer surface of the protruding portions and the inner edge portion of the second cabinet, wherein a top of each of the plurality of convex portions is formed in a tapered or arcuate shape.
2. The cabinet for acoustic equipment according to claim 1 , wherein the convex portions are provided integrally with the outer surface of the protruding portion.
3. The cabinet for acoustic equipment according to claim 2 , wherein the plurality of convex portions are provided at the plurality of positions on the outer surface of the protruding portion at intervals preventing the edge portion of the opening from drooping down.
4. The cabinet for acoustic equipment according to claim 1 , wherein the convex portions are formed in a backward and forward elongated linear shape or in a spherical shape.
5. The cabinet for acoustic equipment according to claim 1 , wherein each of the convex portions includes a pair of projections provided at two adjacent positions, and a top portion of each of the pair of projections is formed in a tapered or arcuate shape.
6. The cabinet for acoustic equipment according to claim 5 , wherein each of the projections is formed in a backward and forward elongated linear shape or in a spherical shape.
7. The cabinet for acoustic equipment according to claim 1 , wherein the protruding portion is provided over upper, left, and right sides of the first cabinet; the convex portions are correspondingly arranged at least two positions on each of the upper, left, and right sides; and rib projecting pieces are superposed on the reverse surface of the protruding portion at a position intermediate between the convex portions arranged at the two positions, the rib projecting pieces are provided on the second cabinet.
8. The cabinet for acoustic equipment according to claim 7 , wherein each of the rib protruding pieces has a function of sliding on the reverse surface of the projection portion to guide the protruding portion to the inner side of the edge portion of the opening while outwardly warping and deforming the protruding portion when the protruding portion is fitted to the inner side of the edge portion of the opening, and the rib projecting pieces outwardly press the protruding portion, and whereby the protruding portion is brought into contact with the reverse surface of the edge portion of the opening.
9. The cabinet for acoustic equipment according to 8 , wherein a guide surface slanted rearward upward is formed on a tip of each of the convex portions.
10. The cabinet for acoustic equipment according to claim 1 , wherein the first cabinet and the second cabinet are made of synthetic resin moldings.
